Polyjuice Potion

Ivan was frustrated that, according to the progress he had made in the Gryffindor Lounge and the boys' dormitory, he would not be able to push his progress past seventy percent even if he completed all three colleges.

In other words, he always had to go to one of the girls' dormitories and the Basilisk Chamber…

After a moment's hesitation between life and integrity, Ivan decided against it.

The following Saturday was a perfect opportunity for Hermione to read in the library.

With that in mind, Ivan scooped up a large amount of the potion from the cauldron and placed it in a transparent glass reagent. He then removed the brown hair from his pocket and dropped it into the potion.

The potion, which was originally as dark as thick mud, suddenly bubbled like boiling water. After a while, it turned bright brown and settled.

…

Saturday morning,

Ivan, who had been waiting in the lounge for some time, managed to catch a glimpse of Hermione, who was reading a book.

"Ivan, do you want to go to the library with me?" Hermione asked after greeting him happily.

"No, Ron asked me to play Wizard's Chess in the dorm, so I'm not going today." Ivan shook his head, declining Hermione's invitation.

Disappointed, but not overly concerned, the young witch went on her own way with her daily studies.

Ivan waited for a while, then took out the Marauder's Map to make sure Hermione was in the library before heading to the Room of Requirement.

Hmm… Tastes okay…

Ivan smacked his lips, somewhat surprised.

This was not the first time he had drunk Polyjuice Potion. According to the book's description, it was supposed to be quite unpleasant.

He recalled, however, that everyone seemed to smell different…

Before Ivan could think any further, he felt a tingling sensation in his body.

It was the exact opposite of the last time she transformed into Walker, and Ivan was acutely aware that she was shrinking and becoming shorter, as her short hair elongated and curled over her shoulders, turning from gold to brown…

When Ivan opened his eyes again, his clothes were noticeably looser.

Ivan pulled out his wand and tapped the nearest mahogany table, turning it into a large full-length mirror.

The figure in the mirror looked exactly like Hermione.

Of course, there was something wrong with his clothes…

Ivan suddenly thought of the devastating problem of not having a girl's uniform!!

"If I'd known, I'd have asked Tom to teach me how to speak snake, and I'd have gone to the Chamber of Secrets!" Yvonne scowled at "Hermione" in her boys' school uniform.

However, Ivan sighed and resigned himself to his fate. He used the Transfiguration Charm to modify the uniform according to his impression of girls.

This was because Ivan was not sure if he would be able to learn the language on his own, and his impression was that Dumbledore was the only one who could understand it on his own.

The rest of the group were born with Voldemort's blood, inherited from their ancestors, and Harry's was due to Horcruxes.

Furthermore, Tom's willingness to teach was another matter.

"Well, it's supposed to be like this. The skirt is too short, and it's perfect for the knees, and the collar needs to be altered…" Ivan repaired it with a Transfiguration Charm, trying to recreate Hermione's outfit as best he could.

Fortunately, Hermione was not the type of witch who liked to dress up, so she usually wore the standard school uniform.

After changing her clothes, Ivan looked into the full-length mirror again. He felt that the little witch in front of him was a little different from the Hermione he remembered, and it took him a while to slap his head…

Just a few more books!

…

In the morning, in the Gryffindor Restroom, Harry and Ron play a deluxe version of Wizard's Chess given by Ivan, while the Unicorn and the Thestrals fight for their lives on the tiny checkerboard hill.

"Harry, you suck at chess," Ron said as he kicked a bearded Dumbledore off the board.

Ron had to admit that seeing this gave him a sense of accomplishment, as if he had actually won the Wizarding War.

"Ron, you're too good. Next time, you should play with Ivan." Harry put away the broken pieces and shook his head.

"I'd have to be able to find him," Ron grumbled.

During the first few days of school, Ivan seemed to have vanished into thin air, except when he was in class or sleeping.

Ron was cleaning the board when he turned around and saw Hermione coming into the lounge with a book.

"Hermione, have you seen Ivan today?"

"Yes?" Yvonne was stunned. I'm right here, aren't I?

Ivan immediately realised the change in his status and, recalling Hermione's tone, snorted and glanced at them.

"How would I know where he went…"

After saying that, Ivan felt embarrassed. He felt that it was embarrassing to imitate a little girl's tone, so he hurried towards the girls' dormitory.

Harry and Ron didn't see anything wrong with this, although they had a vague feeling that Hermione was having a bad day…

Ivan was relieved to be away from them.

He did not expect to have the misfortune of running into Harry and Ron when he was checking the Marauder's Map in the Room of Requirement.

Yvonne thought about it for a moment and decided that she had not given anything away.

Harry and Ron are unlikely to talk about their usual conversations with Hermione…

In fact, Ivan had previously considered using Polyjuice Potion to disguise himself as a girl he did not know, but thought better of it, as he would be easily exposed if he met a close friend.

Ivan, on the other hand, felt that he knew Hermione well enough to know that she didn't have many friends in the girls' circle, or she wouldn't be hanging out with the three boys every day.

While she was thinking, Ivan had unknowingly entered the girls' dormitory.

Two or three groups of young witches passed him, chatting and laughing, the smell of various perfumes mixed in with the occasional playful junior girl…

Ivan looked straight ahead. He had come to explore this mysterious castle, and he had only just arrived…

It was only when the other party greeted him that Ivan would smile and nod in response…
